Get last boot time for server list and Export to csv file

Hi,

I am a newb when it comes to scripting/powershell.  I have a PS script to read from a list of server names in a txt file and return the last boot time information for each server.  The script works great except I would like to get that information exported into a csv file so I can import it into excel and be able to sort it.  The Main thing that I want to display is just the server name and the last boot date.  my script is as follows...

$Servers = Get-Content “ServersTest.txt”  

foreach($Server in $Servers)  
{  
#CREATE A WMI QUERY AGAINST THE CURRENT $SERVER NAME
    $wmi=Get-WmiObject -class Win32_OperatingSystem -computer $Server 
    
    #THE LAST BOOT TIME COMES BACK IN A LONG FORMAT SO CONVERT IT TO A VALID DATE TIME AND ASSIGN IT TO $LASTBOOTTIME 
    $lastBootUpTime=$wmi.ConvertToDateTime($wmi.LastBootUpTime)
    
    #CALCULATE TIME SINCE LAST BOOT
    $now = Get-Date
    $upTime = $now - $lastBootUpTime
    $days = $Uptime.Days
    $hours = $Uptime.Hours
    $min = $uptime.Minutes
    $sec = $uptime.Seconds
    
    #DISPLAY RESULTS
    Write-Host "SERVER NAME:" $Server "Last Boot Time:" $lastBootUpTime
    Write-Host "HAS BEEN UP FOR: " $days "DAYS " $hours "HOURS " $min "MINUTES" $sec "SECONDS" 
} 
 

Any Help would be greatly appreciated.

Thank you,

Kevin
